T. obovata. (New species.) 1 Verrt. name — io, Mumbariba. A tree 612 metres high. Leaves more or less crowded toward the end of twigs, which are leafless below ; 
leaves 7-15 c.m. long, 4-6 c.m. wide, obovate to elliptical, bluntly pointed, tapering below, pubescent below, ultimately glabrescent above. Petiole 10-15 m.m. long. 
Fruits 3-4 c.m. long, 2 c.m. wide, 2-winged, tapering to the apex and tapering to the 1 c.m. peduncle. Frequent in Magenja da Costa. Sim 5672.

131. LUMNITZERA. One African species, as under:— 
L. racemosa, Wind. Vern . name — 10, Mormoni. A saline or mud mangrove, shrub or tree up to 10-12 metres high, with alternate, succulent, leathery, obovate, 
crenate leaves 3-5 c.m. long, 3 c.m. wide, tapering to the short petiole. Spikes axillary, 3-8 c.m. long, 5-10 flowered. Ovary 1-2 c.m. long, 4 m.m. diameter 
compressed, somewhat curved, surmounted by the 5 short deltoid calyx-teeth, i-celled, with 5 pendent ovules, and supported at the base by an attached bract on 
each side. Petals 5, 5 m.m. long, bluntly pointed, concave, white. Stamens 10, exserted, as long as the conical pistil. Seeds 5, linear. Abundant among man- 
groves on tidal mud from the Zambesi northward, usually much-branched, bushy, and brittle.

FAMILY XXXII.— RHIZOPHOREAi. 
Glabrous trees or shrubs, often confined to tidal mud, with opposite or ternate simple leaves, axillary perfect, regular flowers, inferior or more or less superior 2 or more 
celled ovaries, and ovules 2 in each cell, pendulous from the top. Stipules interpetiolar, caducous. Stamens 2-3 times the number of the petals. A small group, some members 
of which are present on most tropical shores ; others occur in forests away from as well as on the coast. 
132. RHIZOPHORA. Flowers leathery. Calyx-tube short, bracted, limb 4 parted. Petals 4, entire; stamens 8, almost without filaments, perigynous, the anthers long, 
many-celled. Ovary inferior, 2-celled ; cells with 2 pendulous ovules. Fruit leathery, i-celled, i-sceded, germination taking place before the fruit drops. Leaves 
opposite, leathery, with caducous interpetiolar stipules. Represented by one variable species or several species, on all tropical shores. 
R. mucronata, Lam. Vern. names— 1 , Red Mangrove ; 2, Mangle (which applies also to other mangroves); 4, Stobani or Shi-thlo-bani ; Staak ; 10, Infise. A tree 
8-12 metres high, confined to tidal mud. Leaves opposite, elliptical, bluntly pointed, pctiolate, 7-10 c.m. long, 4-6 c.m. wide. Stipule intra-axillary, 7-10 c.m. long, 
sheathing. Cymes few-flowered, bracted. Calyx 4-fid, inferior; segments 15 m.m. long; petals shorter and smaller, and with 2 sessile lanceolate stamens opposite 
each. Fruit oblong, leathery, at length pierced by the radicle of the germinating embryo which continues to grow downward, sometimes for 30 c.m. before the fruit 
drops, and then on dropping pierces the soft mud and continues separate existence. Yields the mangrove bark of commerce, an article of export for tanning 
purposes, but often adulterated with other kinds. Frequently supported by adventitious roots from up the stem. Present on all tidal mud flats in the Province, but 
often only in young condition through the older material having been cut out for poles or bark. Now protected under Government regulation, and seeds are being 
planted to increase the stock. Grows rapidly and yields sound durable poles of red timber up to 30 c.m. diameter, or sometimes more. 
R. racemosa, Meyer. A Tropical American species mentioned in “Annuario de Mocambique,” 1908, is distinguished by having its flowers in paniculate divaricate 
shortly-jointed many-flowered cymes, and is not so far as I know found in the Province.

133. BRUGUIERA. Glabrous leathery trees inhabiting tidal mud. Flowers leathery, 2 5 c.m. long and wide, the calyx-tube without bracts, and having the sunk ovary at 
its base. Calyx-limb expanded, about 12-cleft; petals as many and of equal length, bifid, leathery, bearded along the margin, and with the lobes folded together 
enclosing the 2 stamens, which are set in pairs opposite each petal. Filament 12 m.m. long, anther 1 c.m. long ; style 2 c.m. long, stigma 3-4 lobed. Ovary 2-4 
celled, sunk in the calyx-tube. Fruit 12 m.m. long and wide, crowned by the calyx-lobes, and afterwards having the germinating embryo hanging 10-30 c.m. pod- 
like below. 
B. gymnorhiza, Lam. Vern. names are shared with Rhizophora mucronata, from which by natives and even by bark collectors it is not distinguished, the general 
appearance being almost identical. Leaves opposite, 7-10 c.m. long, 2 ‘5-4 c.m. wide, elliptical, acute, and tapering to the petiole. Calyx-tube embracing the ovary
